Yes, we agree - and this is the aim. Unfortunately due to timezone differences between various teams involved, the IDE installers have become available before the information on the new release could be sent live. The updated release notes should become available shortly. But in the meantime, the announcement (which gives the same details as in the release notes) is now available within the community at:
MCUXpresso IDE v10.1.1 Now Available
Note the release notes are also contained within the product install directory (the "readme" file), though I recognise that you have to have installed the product to see that version.
Regards,
MCUXpresso IDE Support
